Sauce good with fish around five (5)
I believe the answer is:
gravy
'sauce' is the definition.
(gravy is a kind of sauce)
'good with fish around five' is the wordplay.
'good with' becomes 'g' (I can't explain this - if you can you should give a lot more credence to this answer).
'fish' becomes 'ray' (ray is a kind of fish).
'around' means one lot of letters goes inside another.
'five' becomes 'V' (Roman numeral).
'ray' placed around 'v' is 'ravy'.
'g'+'ravy'='GRAVY'
Can you help me to learn more?
(Other definitions for gravy that I've seen before include "Meat jus" , "Kind of train?" , "Meat juices after cooking" , "Sauce made with meat juices" , "Sauce from meat juice" .)
